So far this is what I could find.
https://steamcommunity.com/id/RVesta - Supposed brother's account.
https://steamcommunity.com/id/Rtorva - His current account.
https://steamcommunity.com/id/Rpernix - Denies this account.
All start with the prefix R then the name. All accounts have a ban of some sort. Whether in CS:GO or other games. All of the accounts were friends until they were listed here where Dizzy unfriended them. Dizzy stated that he had added them to try and contact them and I quote "[15:38] Dizzy: So i can get some answers on why im banned with them" although none of them are banned with KZG. Implying he contacted them AFTER his KZG ban on the 21st, but he has been friends with them for a lot longer than that. In fact, he was friends with Rpernix for 1,436 days, Vesta for 1,189 days and second Vesta for 1,034 days.
The main account I found interesting was the Rpernix account.
It was registered under the alias Dizzy and used Dizzy until the 19th of December 2017 where 6 name changes were made in quick succession. It had also used the name Lysergic on the 3rd of Feb and Torva on the 6th of Feb. Torva being Dizzy's current name on his steam profile.
Lysergic was used to cheat in our 1v1 arena server on 13/03/18 and was banned by admin B1N. That account listed below also curiously uses the name Dizzy currently.
